Module graphics 

Graphics builtins — high-level R plotting functions that accumulate PlotItems in the interpreter’s PlotState, then display via egui_plot (when the plot feature is enabled) or print a helpful message (when it is not).

Modules

color

Color palette generation functions — rainbow(), heat.colors(), terrain.colors(), topo.colors(), cm.colors(), gray.colors(), hsv(), hcl(), and colorRampPalette().

Functions

builtin_axis 🔒

Add an axis to the current plot.

default_palette_color 🔒

Default palette: R’s default color cycle.

df_get_column 🔒

Look up a column in a data frame (RList) by name.

ensure_plot 🔒

Ensure a current plot exists, creating a new one if needed.

extract_doubles 🔒

Extract a numeric vector from an RValue, filtering out NAs.

extract_limits 🔒

Extract a (lo, hi) range from a two-element numeric vector.

flush_plot

Public API: flush any accumulated plot to the GUI thread. Called by the REPL loop after each eval to auto-display plots.

interp_abline 🔒

Add horizontal, vertical, or slope-intercept lines to the current plot.

interp_barplot 🔒

Create a bar plot from a numeric vector.

interp_bmp 🔒

Open a BMP graphics device.

interp_boxplot 🔒

Create box-and-whisker plots.

interp_dev_cur 🔒

Return the current graphics device number.

interp_dev_list 🔒

List all open graphics devices.

interp_dev_new 🔒

Open a new graphics device.

interp_dev_off 🔒

Close the current graphics device.

interp_hist 🔒

Compute a histogram and display it as a bar chart.

interp_jpeg 🔒

Open a JPEG graphics device.

interp_legend 🔒

Add a legend to the current plot.

interp_lines 🔒

Add connected line segments to the current plot.

interp_pairs 🔒

Scatterplot matrix — plots all pairwise combinations of numeric columns.

interp_pdf 🔒

Open a PDF graphics device.

interp_plot 🔒

Create a scatter plot, line plot, or combined plot.

interp_png 🔒

Open a PNG graphics device.

interp_points 🔒

Add points to the current plot.

interp_svg 🔒

Open an SVG graphics device.

interp_title 🔒

Set or update plot titles.

parse_color 🔒

Parse an R color specification to RGBA.

parse_color_string 🔒

Parse a color string: named color or hex.

parse_hex_color 🔒

Parse a hex color string like “#RRGGBB” or “#RRGGBBAA”.

percentile 🔒

Compute a percentile from sorted data using linear interpolation.

rhs_symbol_name 🔒

Extract a simple symbol name from a formula side (lhs or rhs).

send_current_plot 🔒

try_extract_doubles 🔒

Try to extract a double vector from an optional RValue.
